Kurt Cobain‘s daughter Frances Bean Cobain has spoken out for the first time around the release of Cobain: Montage of Heck, the new documentary about her father.

Talking to Rolling Stone, the 22-year-old visual artist and executive producer on the new movie revealed she is not a fan of her father’s music.

“I don’t really like Nirvana that much,” she commented. “Sorry, promotional people, Universal. I’m more into Mercury Rev, Oasis, Brian Jonestown Massacre. The grunge scene is not what I’m interested in.” However, she added that ‘Territorial Pissings’ is “a fucking great song”.

Cobain also spoke about hanging out with the remaining members of Nirvana. “Dave [Grohl], Krist [Novoselic] and Pat [Smear] came over to a house where I was living,” she recalled. “It was the first time [they] had been together in a long time. And they had what I call the ‘K C Jeebies,’ which is when they see me, they see Kurt. They look at me, and you can see they’re looking at a ghost. They were all getting the K C Jeebies hardcore. Dave said, “She is so much like Kurt.”… But I was glad they came over. It was a cool experience, like having a Nirvana reunion minus one. Except for his spawn.”

Meanwhile, Brett Morgen, the director of Cobain: Montage of Heck told NME that the Nirvana frontman “died of a broken heart”. Speaking in the new issue of NME, which is on newsstands now and available digitally, the director details finding Cobain’s “actual suicide letter” and how, following his research on the Nirvana frontman, it “made no sense”.

He revealed: “I found his actual suicide letter, which was unexpected. I just opened up this heart shaped box and there it was. And I was like ‘Based on everything I’ve witnessed, this makes no sense.’ Kurt didn’t have a problem with quitting music; he talked about it openly. If he wanted to stop performing, he would just stop. Nothing was leading up to that suicide letter.”

In an interview with Morgan towards the end of the documentary, Courtney Love reveals Cobain tried to kill himself in Rome on March 3, 1994 because he knew she was “thinking about” cheating on him.

According to Morgan, it was this that contributed to the singer’s suicide on April 5, 1994. He stated: “You can see in the film he put all his eggs in one basket. And so when that was broken in his mind, there was this sense of humiliation. Kurt Cobain died of a broken heart. He thought his wife cheated on him, and her and Frances were all he had. The film invests a lot in trying to understand why Kurt would react the way he did to betrayal. We try to find the square root of it.”
